Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients with chest pain that continued longer than 30 minutes and with ≥ 2 mm ST elevation in ECG at least in two adjacent derivations were diagnosed with an acute STEMI. In all patients, at least two-fold increases were seen in serum CK-MB levels compared to normal values.Having acute STEMI for the first time was stipulated for inclusion in the study.

Exclusion criteria

  • Subjects with known allergies to aspirin and clopidogrel, inadequate echocardiographic images, malignancy, a previous cerebrovascular event, renal dysfunction (creatine level > 2.5 mg/dl), a previous MI, or a history of cardiogenic shock as well as those who refused to participate in the study were excluded.

Primary outcomes

  1. Major Adverse Cardiac Events

    the presence of a fQRS at 48 hours after primary PCI is a significant parameter in predicting adverse cardiovascular events;

Secondary outcomes

  1. Q Wave and QRS distortion for predicting major adverse cardiac events

    the presence of a fQRS is a more sensitive and specific parameter in predicting development of adverse cardiovascular events than Q wave and QRS distortion; and compared to Q wave, fQRS correlated more significantly with the presence of a scar
